Knowledge that Transforms

Using multiple administrative data sources from Norway, we examine how firm performance changes after entrepreneurs become parents.Female-owned businesses experience a substantial decline in profits, steadily decreasing to 30% below baseline ten years post-childbirth.In contrast, male-owned businesses show no decline, often growing in revenues and costs after childbirth.The profit decline for female-owned firms is most pronounced among highly capable entrepreneurs, women who are majority owners, and those with working spouses.Entrepreneurial effort is key to performance, and our findings suggest that time demands from childbirth and childcare are a significant determinant of the decline in firm profits.
